SLlTTER-GRINDEM.

SPECIFICATION forming part of Letters Patent No. 766,927, dated August9, 1904.

Application filed January 23, 1904. Serial No. 190,259. (No model.)

To all whom, it may concern/.

Be it known that l, ALBERT BESS, a citizen of the United States,residing at Hamilton, Ohio, have invented a new and useful linprovementin slitter-Grinders, of which the following is a specification.

My invention relates to slitter-grinders of the class adapted to grindpaper-mill slitters or other articles; and the objects of myimprovementare to provide means to grind slitters without the necessityof removing them from the rotative shafts whereon they are mounted, tomount a grinding-wheel directly on the shaft of an electric motor whichis mounted on a universally-adjustable bracket, and to providescrew-feed mechanism therefor, whereby the grinding-wheel may beadjusted in any angle or position to the object to be ground and movedin contact therewith.

These objects are attained in the followingdescribed manner, asillustrated in the accompanying drawings, in which Figure 1 is a plan ofmy improved device; Fig. 2, a side elevation while in operativeposition, and Fig. 3 a longitudinal section of the feed mechanism.

In the drawings, 4 represents the top slit ter-blade, and 5 the bottomcup-slitter, mounted, respectively, on rotative shafts 6 and 7 in theordinary manner. Stationary shaft 8 is removably secured parallel toshafts 6 and 7 and at any desired distance therefrom.

Split sleeve 9 is adjustably secured on shaft 8 and at right anglesthereto by means of seat 11, formed therein, and cap 12, which isremovably secured thereon with cap-screws 13. Cylindrical arm 14 isclamped in sleeve 9 by means of hand-screw 15 and is longitudinally androtatively adjustable therein. Split collar 16 is securely fastened toone end of said arm and at right angles thereto by means of transversepin 17 or otherwise.

Bushing 18 may be maintained in different positions of rotativeadjustment within split collar 16 by means ofhand-screw 19 in saidcollar. Lug 21 extends inwardly from one side of said bushing andterminates in a threaded nut 22, concentric with its axis. Feed-sleeve23 is formed with a longitudinal slot 24: for the movement therein oflug 21 and is longitudinally movable within bushing 18 to the extentpermitted by the slot. Feedscrew 25, which is extended axially throughthe sleeve and engages nut 22, serves to actuate the sleeve as desired.Hand-wheel 26 is mounted on one end of the feed-screw, together withcollar 27, which prevents anylongitudinal movement of the screw withinthe sleeve.

Flange 28, formed on one end of sleeve 23, serves fora seat whereonelectric motor 29 is secured, with its shaft 30, at right angles to thesleeve bymeans of cap-screws 31. Grinding-wheel 32 is mounted on one endof the motor-shaft, and wires provide the motor with an electric currentfrom a generator. (Not shown.)

In operation the universal adjustment of the bracket by which the motoris attached to shaft 8 permits the grinding-wheel to be placed in anydesired angle or position to the slitter and to be fed in contacttherewith by means of the screw-feed mechanism.

Slitters may be ground more accurately while in position on their ownrotating shaft than after being removed therefrom. Where provision hasbeen made in the construction for the independent rotation of either ofthe slitter-shafts, the other one may be secured against rotation andused for the attachment thereto of the bracket during the grindingprocess of the slitters on the other shaft in stead of providing aspecial shaft 8 for the purpose.

Having fully described my improvement, What I claim as my invention, anddesire to secure by Letters Patent of the United States,

1. The combination with an arm, and means arranged to secure it to alixed shaft in dil'ler- 9 cut positions of longitudinal or rotativeadjustments thereon and with the arm in differ ent positions oflongitudinal or rotative adjustment, of feed mechanism mounted at rightangles and rotatively adjustable on the arm,

an electric motor mounted on said mechanism, and a grinding-wheelmounted on ,the motor-shaft.

2. The combination with an arm, and means arranged to adjustably secureto a fixed shaft,

of screw-feeding mechanism mounted at right cured in the sleeve, and acollar secured at angles on the arm and rotatively adjustable, rightangles on the arm, of a bushing adjust- IO an electric motor secured tosaid mechanism able rotatively in the collar, and screw-feed and agrinding-Wheel mounted on the motormechanism adjustable axially in thebushing.
